Entrance hall of the ICMS Workshop

Multiscale methods and high performance computing

May 07, 2014 - May 09, 2014

ICMS, 15 South College Street, Edinburgh, EH8 9AA

Organisers:  Assyr Abdulle (Ecole Polytechnique Fédérale de Lausanne (EPFL))
                  Andreas Dedner (University of Warwick)
                  Paul Houston (The University of Nottingham)

The interplay between the development of numerical algorithms for problems with multiple scales and their implementation in a high performance computing (HPC) environment is the focus of this workshop.

Recent developments in numerical algorithms for partial differential equations with multiple spatial or temporal scales will be discussed, including numerical homogenization methods, domain decomposition methods, multilevel Monte Carlo methods, time stepping algorithms for multiscale flow problems. Challenges in the implementation of novel algorithms in an HPC environment will be addressed.

This workshop is sponsored by NAIS (the Centre for Numerical Algorithms and Intelligent Software)
